MACHINE FOR ATTACHING SHEETS OF PAPER fag a Tod/ll whom, it may concern:

Be it known that I, ARTHUR J. FARMER, a citizen of the United States, residing at De: troit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement iii-Machines for Attaching Sheets Paper Together; and I declare the following to be a full, clear, and exact descri tion 1 of the same, such as will enable others s "lled through such t uous roll, afterward severed into sheets cor- 2O responding in size with that of the sheets of in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in machines designed to secure together sheets of .paper by automatically applying an adhesive substance along their edges while passing the machine, the construction being at one of the sheets may be a contin- 7 paper attached thereto.

adhesive su The object of my invention'is to construct a machine capable of attaching together sheets of pa er along one of their edges by an bstance automatically applied to the paper as it travels through the machine,

the construction being such that the paper is cut into sheets of predetermined size before being discharged from the machine. The uses 'to which these attached sheets of paper are put demand that oneof the sheets shall be relatively lighter or' more transparent I I out before being discharged from the machine.

than the other, and in designing this machine it has been determined t at the lighter or more transparent pa er should be in the form of a continuous 'ri bon or roll, while the heavier or more opaque aper is preferably in the form of cut sheets 0 a size corresponding with'that into which the ribbon ofpaper is It is apparent, however, that both the opaque and transparent papers may be continuous rolls to be cut into sheets of predetermined 4 size before being discharged by the machine.

The roll of paper H j ,havin been mounted in the bracket A, the a end 0 the ribbon of paper is threaded around the idlers a a, between the gumming-roll Q I and the guide-roll 0, between the feed-rolls G andF along the belt I", and between the auxiliary feed-rolls I and I to a point on a line] with the cutting edge J. The loose sheets to "be attached to the ribbon of paper,

are laid on the deliveryetable A and fed manually sheet by sheet to the feed-rolls and G, the shoulder g of the feed-roll G [I serving as an abutment or guide against which the sheet is forced. The machine having been put in operation, the rack-bar I),

Y travels upward, causing the gear E to rotate. This gear, being loosely mounted on the shaft f of the feed-roll F, causes the spring-actuated dog E, secured thereto, to travel within the I (clutch-sleeve F until the'dogrides over the v1" shoulder f, formedin the sleeve. This movement is so timed that the rack-bar has now reached the limit ofits upwardtravel, While the shoulderg of the feed-roll G has been brought to the positionshown in Fig. 3 of the drawings. The springdog having engaged the sleeve F, which is keyed to the roll shaft f, the rack bar in -itsdownward movement-causes theclutch to rotate the gear F which in turn meshing with the gear G, operates the roll YG'in'hk'e manner. ;As the roll G rotates the circular portion of its pe-.

riphery immediately following" the shoulder 9 en ages the loose sheet between it and the pass to the cuttingeknife K. At this point the knife K, operated by means of thebellcrank lever M, controlled in turn by the cam N, forces the knife downward, severin' the sheets from the ribbon of paper and de ivering them upon the table A; 'As the paper passes around the guide-roll a thegummin g wheel fed from the well 0 applies along its edge the liquid adhesive, by which the loose sheet is attache'd't'o the'ribbonof paper:
